Unicorns were first mentioned in Greek mythology. Then they survived the heydays of both Greece and Rome,to become the most important imaginary entity of the Middle Ages. They were still around during the Renaissance and have survived into modern times both as romantic figures and cartoon characters.
Then and now, the Unicorn has been the quintessence of purity and grace. Its spiral horn was believed anciently to have magical abilities to "heal" poisoned waters and remedy disease. Part of the mythology was that only a virgin could capture one of this rare breed. Throughout time, they have remained impervious to human capture. But if you are a fan of Unicorns, you can easily keep the image alive by making a choice among these magnificent portrayals to add to your personal checking supplies.
